Schneider Electric's Harmony XVB7 series of modular signal towers, which can be individually configured, are visual and acoustic signalling devices that reliably indicate the operating processes or conditions of a machine or application. In addition to their modern design, the signal towers with a 70-mm diameter are characterised by an energy-saving LED technology with optimum brightness, which enables an excellent 360 degree visibility. Thanks to its simple, tool-free installation, the robust XVB7 signal tower (up to IP65/IP66) is suitable for many different applications, such as automotive, machine tools or conveyor technology.
